Multifunctional integrated gasification furnace with rotary furnace core air supply and simple scraper dust removal

Abstract

The invention provides a multifunctional integrated gasification furnace with rotary furnace core air supply and simple scraper dust removal, relating to the technical field of environment friendliness. The gasification furnace is characterized by adopting the rotary air supply furnace core, and the waste combustion gasification interface is a refractory material layer formed by embedding ceramic air supply nozzles in the rotary furnace core cone surface instead of on the metal furnace chassis, thereby greatly prolonging the service life of the metal furnace chassis. A dust scraper is arranged on the furnace chassis, the lower part of the furnace chassis is provided with a dust receiver, one side of the dust receiver is provided with a closed dust falling tank, and the bottom of the dust falling tank is provided with a screw conveyer which can convey the collected furnace dust to the inlet of the incinerator dust feeder, thereby enhancing the environment friendliness of facility operation and improving the working environment.

Description

technical field [0001] The invention relates to the field of environmental protection technology, in particular to a multifunctional integrated gasifier with a rotary furnace core for air supply and a simple scraper for ash removal. Background technique [0002] With the continuous growth of the global economy and the acceleration of urbanization, the incremental production of medical waste, other hazardous waste and domestic waste and the resulting environmental pollution and human health problems have become common problems facing the world. Therefore, the ultimate goal of solid waste treatment and disposal is to realize the harmlessness, reduction, and resource utilization of solid waste. [0003] Gasification is a thermochemical disposal process between incineration and pyrolysis. It can react the organic components in the waste with the gasification agent in an oxygen-deficient atmosphere to generate synthesis gas, while the inorganic components are removed in the form...

AI Technical Summary

Problems solved by technology

However, there are still many deficiencies in the common solid waste gasification process and the design of the gasifier structure

For example, the traditional gasification fixed bed tends to form a local high temperature zone at the place where the air is injected and where the combustion is intensive, resulting in uneven temperature distribution and high temperature sintering, which affects the normal operation of the gasifier

Generally, there are no movable parts inside the gasifier, so it is difficult to improve and solve the problems of uneven temperature distribution and high temperature sintering

Furthermore, most gasifiers feed materials from the side wall of the furnace, which easily leads to uneven accumulation of materials, causing "bridging" in the material layer, and affecting the normal operation of the gasifier.
